440 Butler

Investigating the butler's case, Wallace seemed to have a breakthrough this time.

Undoubtedly, this was a significant improvement for him.

He did not blindly start his investigation. The first step he took was to think about which corner of the world the butler's family might be in now.

After all, after the death of Isabella Piper, the butler's whereabouts in the country were unknown. Wallace tried to consider the possibility of them immigrating to other countries.

Wallace began by examining the international trade dealings of the butler's family back then.

The butler's family was also involved in international business, having trade networks worldwide.

However, if carefully examined, one could discern their preferences for specific countries within these intricate networks.

Following his thought process, Wallace eventually narrowed down a list of possible immigrated countries.

The butler valued the quality of life greatly.
